HDMI 2.0 version coming soon.


As some of you may or may not know, the next generation of the HDMI specification, HDMI 2.0 is currently being finalized.

The HDMI forum has been meeting over the past months to determine the direction HDMI should go in the future. The two directions put forth included (a) an improved TMDS 6Gbps per lane proposal backed by Silicon Image and almost all of the TV manufacturers and the (b) Micro-Packet proposal led by Apple, Intel, AMD and others to make use of existing Displayport technology. While it was expected to be a close call between the two, the enhanced TMDS 6Gbps approach outperformed the Micro-Packet path. As of this writing, the enhanced TMDS 6Gbps per lane (18Gbps total) will be the protocol for HDMI 2.0.

In addition to the higher data rate, there are expected to be additional features which may include additional 3D functionality, more than 8 channels of audio, CEC standby and wakeup and more.

Keep in mind this is a specification only and there are few current products that could natively meet all of these new specifications anytime soon. In fact, there are still many features in the current HDMI specification that still have yet to be realized by hardware manufacturers to date. As was the case with 1.3 to 1.4, this new specification will serve as a roadmap to future functionality and it will take some time for the manufacturers and technology to catch up in every day use.

The official HDMI 2.0 specification is expected to be released by the end of 2012 with the CTS compliance testing specification expected in February or March 2013.

We will of course keep you posted as we learn more details concerning HDMI 2.0.
